Application filed June 21,1900- Serial No. 21.074- (llo moclold .0 Mwhom 1115 may concern.-

Be it known that 1, WILLIAM HENRY FRAN- 018, a citizen of the UnitedStates, residing at \Vilmington, in the county of Newcastle and State ofDelaware, have invented certain new and useful Improvements in Clampsfor Pages of Type; and it do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appcrtains to make and use thesame.

it is a common practice in printing establishments to tie a page of typewith a cord or string preparatory to im posing it; and hence myinvention has for its object to produce a temporary binder orclamp'fastener for pages of type that will hold the types composing thepage securely in place and that can be more readily and quickly appliedand removed than a cord, thereby making it more convenient to makecorrections; and my invention consists, essentially, of a clamping frameor band having movable heads or members that are ad apted forlongitudinal or rectilinear movement with respect to each other and theconfined page or body of type, and which members are respectivelyprovided with a toggle lock-joint that comprises a hand operating-leverthat is pivoted in a manner to provide an eccentric movement withsufficient leverage to permit of a sufficient reciprocatory movement orthr w of the sliding parts and which utilizes the pressure conferred bysaid. leverage to securely lock the body of type to which it is applied.

Referring to the accompanying drawings, Figure 1 represents a plan viewillustrating the application or use of my novel page hinder or clamp,showing the operating or looking lovers in a closed position. Fig. 2represents a portion of the frame constituting said pagebinder, whileFig. 3 shows a modified form of said binder or clamp,indicating thelocking lovers in a normally open position.

My clamp or locking-frame consists, essentially, of a metallic frameworkcomprising, preferably, two angle-pieces i3 and 7, which are provided attheir diagonally opposite corners with interlocking joints 8 and 9,which in turn consist, respectively, of interlocking tongues 10 andsockets 11 and which permit it is intended.

of the frame members being assembled so as to stand edgewise and presentflatwise a metal face of a height to make a sufficient support for thetype that is intended to be confined thereby.

The head or end portions of the framework 12 and 13 are formed integralwith the side portions or bars Li and 15 by a right-angle bend thatextends at a length slightly exceeding the width of the page of type forwhich The right-angle bends are formed with a strengthening lip or rib16, as shown.

In order to cause the reciprocation of the sliding members 8 and 9 inand out of locking engagement with the body of type, I provide on therespective side bars intermediate of their ends the following operatingand locle ing mechanism.

17 represents a rocking operating lever or bar that is provided with athumb-piece or car 18 and which is fulcrumed at its lower end in amanner to lie flatwise against the outer face of the side bar, as shown.

Pivotall y united to the rocking lever, to the outer face thereof, isthe reciprocating reachbar 19, that is provided with an offset portionor arm 20 at the point where it is pivotally attached to saidoperating-lever to form a sheave that lies flatwise against saidoperating-lever, thus presenting three thicknesses of the metal plateemployed in the frame structure.

The movement of the lever-bar carries the reach-bar in a reciprocatingmovement forward and backward during the partial rotation of saidlever-bar, and the movement of said lever and bar is limited by thelimitingstop 21, which projects from the side bar through the guide-slot22.

The limiting stop or stud 21 is made to project a distance equal to thethree thicknesses of plate constituting the joint above referred to inorder to present a bearing that will admit of the locking of said framein its entirety in a chase, if desired. It will thus be seen that thehead members may be thrown in either direction by equal movements of thereach-bars upon the simultaneous manipulation of the respectiveoperating lever-bars.

The clamp or hinder will of course be made of different sizescorresponding to the different sizes of pages they are required to beapplied to. y

In Fig. 3 there is shown a modified form of clamp frame, which comprisestwo hinged sections 23 and 24, that are connected by theoperating-levers 25 and 26 in a manner to provide a toggle-joint at thehinged positions and which are shown in normal open position in fulllines and in a closed position in dotted lines.

The operation of the clamp has been indicated in the foregoingdescription; but particularly stated the operation is as follows: Whenthe form has been made and placed in position, as shown in Fig. 1, theframe is adjusted to an open position, as shown in Fig. 3, and placedover and about the body of type, when the levers are depressed until theheads are drawn into operative contact with the end portions or lines ofthe body of type.

In large work the frame may be provided with operating-levers positionedat suitable points on the end bars, and the strengthening-lip may bedispensed with or divided at those points.

Although I have illustrated my invention as applied especially to pagesof type, I do not limit myself thereto and may apply the device hereindescribed to any body of matter or material that is required to be heldsocurely together in the manner prescribed.

Having described myinvention, what I desire to claim as new and usefulis 1. A type-fastening device comprising a rectangular clamping-bandcomposed of two longitudinally movable angular members, and a pair ofoperating-levers respectively fulcrumed fiatwise to the outer face ofeach side bar of the angular members, and a reachbar pivotally united toeach of said operatinglevers, substantially as and for the purpose setforth.

2. A type-fastening device comprising a pair of angle members thatcomprise each longitudinally movable members, having guiding-slots andstop-pins respectively, and means for imparting longitudinal movement tothe respective parts of each member, that comprises a toggle jointedlever, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM HENRY FRANCIS.
